But the most remarkable of these desert superstitions, as suggested by the mention of Lord Lindsay, is one which that young nobleman, in some place which we cannot immediately find, has noticed, but which he only was destined by a severe personal loss immediately to illustrate. Lord L. quotes from Vincent le Blanc an anecdote of a man in his own caravan, the companion of an Arab merchant, who disappeared in a mysterious manner. Four Moors, with a retaining fee of 100 ducats, were sent in quest of him, but came back _re infecta_. 'And 'tis uncertain,' adds Le Blanc, 'whether he was swallowed up in the sands, or met his death by any other misfortune; as it often happens, by the relation of a merchant then in our company, who told us, that two years before, traversing the same journey, a comrade of his, going a little aside from the company, saw three men who called him by his name; and one of them, to his thinking, favored very much his companion; and, as he was about to follow them, his real companion calling him to come back to his company, he found himself deceived by the others, and thus was saved. And all travellers in these parts hold, that in the deserts are many such phantasms seen, that strive to seduce the traveller.' Thus far it is the traveller's own fault, warned as he is continually by the extreme anxiety of the Arab leaders or guides, with respect to all who stray to any distance, if he is duped or enticed by these pseudo-men: though, in the case of Lapland dogs, who ought to have a surer instinct of detection for counterfeits, we know from Sir Capel de Broke and others, that they are continually wiled away by the wolves who roam about the nightly encampments of travellers. But there is a secondary disaster, according to the Arab superstition, awaiting those whose eyes are once opened to the discernment of these phantoms. To see them, or to hear them, even where the traveller is careful to refuse their lures, entails the certainty of death in no long time. This is another form of that universal faith which made it impossible for any man to survive a bodily commerce, by whatever sense, with a spiritual being. We find it in the Old Testament, where the expression, 'I have seen God and shall die,' means simply a supernatural being; since no Hebrew believed it possible for a nature purely human to sustain for a moment the sight of the Infinite Being. We find the same faith amongst ourselves, in case of _doppelgänger_ becoming apparent to the sight of those whom they counterfeit; and in many other varieties. We modern Europeans, of course, laugh at these superstitions; though, as La Place remarks, (_Essai sur les Probabilités_,) any case, however apparently incredible, if it is a recurrent case, is as much entitled to a fair valuation as if it had been more probable beforehand.[Footnote: _'Is as much entitled to a fair valuation, under the lans of induction, as if it had been
